Cannot install due to "no attribute 'DeACSM_Prefs'" error

[gstalnaker]

Bug description

Attempting to install - I've used multiple downloads from the "official" latest v0.0.16, to other downloads found in various submitted issues/comments and from the source using build bundle. All produce this error.

This is one of the reasons why I still haven't fully released the 0.1.0 builds yet - there's issues when updating from 0.0.16 to 0.1.0 sometimes.

You'll need to uninstall the plugin, then restart Calibre twice and only then install the beta to clean up the mess.

Almost got it -- could not install the v0.0.16 version available through the Calibre PlugIns UI, but DID successfully install the v0.1.0 you've made available on another issue here. Created the anonymous AdobeID to use. Unfortunately I have been unsuccessful in adding any .ascm file book to my Calibre installation. I get an item in the Calibre library that is the .ascm file itself and not the book. I think there is another issue that is about this, so I'll go look at it and see if you've provided guidance there. Thanks!

True, on Ubuntu 24.04 + Calibre 7.6 this was the case for me: i had all of the mentioned issues (libcrypto not found, DEASMC_prefs not found , etc) but downloading the latest beta from build #226 AND cleaning out .config/calibre/plugins/ACSMInput AND restarting calibre multiple times fixed the install for me.
